Summary:Chip multiprocessor interconnects have been facing power and performances issues. While Optical Networks on Chip (ONoC) are identified as a possible solution. Recent advances in integration technologies allow stacking optical layers, which leads to the design of highly efficient optical devices avoiding waveguide crossing. The paper presents an Optical Multi-layer Network on Chip called "OMNoC", a novel circuit-switched ONoC relying on this multi-level optical layer design paradigm and based on multi-layer microresonator switches allowing efficient light coupling and low crosstalk. Comparisons with existing ONoCs indicate that OMNoC can achieve low power consumption and chip area.
